Abstract (en)

A conversion device includes: a DC bus provided between a DC power supply and an AC power supply; a first converter provided between the DC power supply and the DC bus to perform DC/DC conversion; a second converter provided between the DC bus and the AC power supply to perform DC/AC or AC/DC conversion; and a control unit configured to selectively cause the first converter and the second converter to operate within one cycle of the AC power supply, to alternately generate a part of an absolute value of an AC waveform, and a DC waveform, as voltage of the DC bus, wherein the control unit adds a compensation value in a positive direction, to a voltage target value for the DC bus, at a timing that should have corresponded to a discontinuity point where the AC waveform and the DC waveform are connected to each other.
